摘要： An interconnection between fully synchronous networks and next-generation frame communications networks is disclosed. A means of bidirectional frame format conversion between a synchronous multiplexing system and a logical multiplexing system is provided, along with a method of transmitting data between different networks on a path as if it were being transmitted in the same network. Further, when converting network control information in an STM network into data suitable for a packet network, even across the boundary of a synchronous multiplexing system and a logical multiplexing system, a unified communication management means is provided over the whole path.

摘要： An interconnection between fully synchronous networks of the prior art and next generation frame communications networks, which is required for the shift to next-generation packet networks and a broader-based connection service, is realized. Here, the first point is that a means of bidirectional frame format conversion between a synchronous multiplexing system and a logical multiplexing system is provided, and a method of transmitting data between different networks on a path as if it was being transmitted in the same network. The second point is that when converting network control information in an STM network into data suitable for a packet network, even across the boundary of a synchronous multiplexing system and a logical multiplexing system, a unified communication management means is provided over the whole path. For this purpose, a hierarchized logical path control method is used wherein, in a network comprising two or more information relay devices having one or more line interfaces, this network performs communication between information relay devices using data packets, and has a means, when performing communication between any two points in the network, to control the path via which the packets pass between arbitrary end points, and the communication control means has a first communication path management function which performs communication management at the connection level which is terminated at the end point of a communication section, and a second communication path management function which performs communication management for each section of a physical circuit or logical circuit which is terminated at each communication section between any adjacent information relay devices in the communication section.

摘要： Provided is a multicast path management method for a connectionless communication. Also provided is a path protection function which is effective when a path has failed. A network is formed by a trunk and a branch path. The multicast path is managed by end-to-end and when a failure has occurred, an instruction is issued from the apex of the multicast tree to respective end-to-end paths so as to switch from the currently used channel to a backup path. Thus, upon failure, an individual path protection can be performed without affecting other parts of the tree to which the same multicast flow as the defective path is distributed or the distribution state of the multicast flow.

摘要： A PON system capable of utilizing the bandwidth of an optical transmission channel in the PON section. In a PON system including an OLT and a plurality of ONUs, the OLT has: a downstream frame processing unit that removes at least part of the header information in a layer 2 header from a downstream frame received from a wide area network, and converts the remaining frame portion into a frame having a header specific to the PON section; and a downstream frame processing unit that extracts a downstream frame portion to be transferred to a user terminal, from a received frame from a PON, and adds the layer 2 header information deleted in the OLT.
